"Love you, dad. #restinpeace," Ellen captioned an Instagram photo of her father's funeral portrait.
The girls recently celebrated their grandpa's 84th birthday together with him in October.
Laura and Vanessa have not yet publicly commented during this time of sadness, but Laura's Austin & Ally co-star Calum Worthy left a sweet comment on their mom's Instagram post.
It's so sweet that he let the family know he's thinking about them during this difficult time, a sentiment all of us Laura and Vanessa fans share.
